Brainley (a brain wearing a set of groucho glasses) and Dobbsey (another brain) are speaking in the foreground. In the background, we see an easel with a painting of a grey blob.
Brainley: Behold, my latest work of art! I call it "Ceci ne pas un cerveau", to evoke a Magritte-inspired surrealism in the viewer!
Dobbsey: But, Professor Brainley, shouldn't that be "Ceci ne'st pas un cerveau"? I think you got the French wrong.
Brainley: Do not trifle with me! This is ART!
